-------------------------------------------------
Hi all, we faced the same problem and I created separated ticket MAPREDUCE-7133
(did not see this ticket before). We can rename the property in TaskAttemptInfo
but as you said this is the incompatible change and this looks like the
workaround. Perhaps, we can to fix the main cause of the problem and save
backward compatibility.
Could someone evaluate the solution and review the patch attached to
MAPREDUCE-7133?
Thanks a lot for any comments.
